Kolkata: Accsuing West Bengal Chief Minister Mamata Banerjee of trying to shield Tapas Pal, who has made controversial remarks, senior BJP leader Siddharth Nath Singh said only an apology was of no use and he should be made to quit as Trinamool Congress MP.

"Two tapes of TMC MP Tapas Pal are out and Mamata Banerjee is still trying to shield him. This is the policy of Trinamool for TMC goons. Only apology is of no consequence, he should be made to quit his parliament seat," Singh told PTI. "West Bengal government should file a criminal case against him," Singh said.
